Despite being one of the most widely viewed 3D movies, and the highest grossing film of all time, viewers still have not been able to buy Avatar on Blu-ray 3D by itself (without paying high prices to resellers) due to an exclusive pack-in deal with Panasonic, but that will change this fall. Fox just announced the Avatar Blu-ray 3D Collector's Edition will debut globally October 15th, and release in North America October 16th. There's no word on any extra special features, as producer Jon Landau indicates in the press release (included after the break) it will contain the theatrical cut of the flick inside special packaging. Originally, the delay in releasing the movie widely on disc in 3D was blamed on a lack of 3DTVs in homes. We'll see if the prospect of watching the $2.7 billion juggernaut "the way it was meant to be seen" according to director James Cameron, nudges more buyers towards a new display this fall. Check below for a video clip of Cameron sharing the news to the movie's fans on Facebook, plus an extra treat that didn't make it into the movie.
